Selective pulse implementation of two-qubit gates for spin-3/2 based
fullerene quantum information processing
M. Feng, J. Twamley
abstract: We propose two potentially practical schemes to carry out two-qubit quantum
gates on endohedral fullerenes $N@C_{60}$ or $P@C_{60}$. The qubits are stored
in electronic spin degrees of freedom of the doped atom $N$ or $P$. By means of
the magnetic dipolar coupling between two neighboring fullerenes, the two-qubit
controlled-NOT gate and the two-qubit conditional phase gate are performed by
selective microwave pulses assisted by refocusing technique. We will discuss
the necessary additional steps for the universality of our proposal. We will
also show that our proposal is useful for both quantum gating and the readout
of quantum information from the spin-based qubit state.
